4. General Information
4.1. DESCRIPTION
The agitators of BCI series are direct motor-driven agitators with a stainless steel base. In spite of being very
compact, these agitators have a bearing suport that is completely independent of the motor. The half shaft is
guided by two bearings that support the axial and radial forces transmitted by the agitation elements. The
agitator shaft is attached directly to the half shaft with two allen pins.
4.2. OPERATING PRINCIPLE
The agitators are normally installed inside the tank either centrally with current deflectors, or offset, so that the
offsetting itself prevents the rotation of the stirred product.
The rotation of the propeller makes the fluid flow to the bottom and then up to the surface of the product along
the walls of the tank. The effect is promoted if the bottom of the tank is curved.
The Lineflux vigorously agitates the content of the tank promoting the mixing of the product while the saw tooth
propeller promotes its dispersion.
4.3. APPLICATION
Its application is for agitation and mix processes on tanks with a maximum volume of 1.500 l and to work with
low-viscosity products.
These agitators are used in the processes of mixing, dissolution, dispersion and maintenance whenever
powerful and high-speed agitation is required in the food processing, cosmetics, pharmaceutical or chemical
industries.
Each agitator has performance limits. The agitator was selected for a given set of mixing conditions
when the order was placed. INOXPA shall not be held responsible for any damage that might be
suffered or malfunctioning of the equipment of the information provided by the buyer is incomplete
or incorrect. (e.g. nature of the fluids or installation details).

5.6. ASSEMBLY
To locate and fix the agitator in the support flange of the tank, the propeller must be removed from the shaft.
Once the base of the agitator is placed on the supporting flange, the fixing nuts and screws will be assembled in
their corresponding holes, without being tightened. When this operation has been carried out, the agitator must
be levelled using the following method:
1. Place a spirit level against the shaft.
2. Check 4 points at 90º to each other around the circumference of the shaft and at the same height.
3. Once the shaft is level, firmly tighten the fixing nuts and screws. Finally the propeller is mounted on the
end of the shaft. Be careful when assembling the shaft not to hit or strain it so as to avoid it being bent.
Force should never be applied to the end of the agitator shaft, as it can easily suffer permanent
damage.
Check the alignment of the agitator shaft with the half shaft once its assembly is completed.
